Abstract
The invention relates to an apparatus for the automatic production of a punch having a sharp cutting edge, especially for label cutting apparatus, made from a punch body provided with an upstanding land. To avoid the former manual finishing of the land produced by etching or by some other manner, a largely automatically operating apparatus is proposed which has a table (6) for the punch body, a tool (56) with a roof-shaped notch facing the table (6), a first drive (64) for the automatic movement of the tool (56) back and forth in the direction of the table (6) and additional drive (15, 37, 51, 62) for the production of relative movements between the table (6) and the tool (56), by means of which the tool (56) can be guided automatically along the land (22) (FIG. 1).
